The paper entitled "Balancing Speed and Coverage by Sequential Seeding in Complex Networks," by J. Jankowski, P. Brodka, P. Kazienko, B. K. Szymanski, R. Michalski and T. Kajdanowicz has been published in Scientific Reports7:891, April 17, 2017. The authors study information spreading in complex networks and introduce a novel approach in which seeds are initiated sequentially. Sequential seeding and a single stage approach are compared using various seed ranking methods and diffusion parameters on real complex networks. The experimental results indicate that sequential seeding delivers better coverage than single stage seeding in about 90% of cases regardless of the seed ranking method used; see https://www.nature.com/articles/s41598-017-00937-8
